Examples

The following code example shows how to implement the ProcessEventFlush method.

// Processes the messages that have been buffered.
// It is called by the ASP.NET when the flushing of 
// the buffer is required.
public override void ProcessEventFlush(
    WebEventBufferFlushInfo flushInfo)
{

    // Customize event information to be sent to 
    // the Windows Event Viewer Application Log.
    customInfo.AppendLine(
        "SampleEventLogWebEventProvider buffer flush.");

    customInfo.AppendLine(
        string.Format("NotificationType: {0}",
        GetNotificationType(flushInfo)));

    customInfo.AppendLine(
        string.Format("EventsInBuffer: {0}",
        GetEventsInBuffer(flushInfo)));

    customInfo.AppendLine(
        string.Format(
        "EventsDiscardedSinceLastNotification: {0}",
        GetEventsDiscardedSinceLastNotification(flushInfo)));

    // Read each buffered event and send it to the
    // Application Log.
    foreach (WebBaseEvent eventRaised in flushInfo.Events)
        customInfo.AppendLine(eventRaised.ToString());

    // Store the information in the specified file.
    StoreToFile(customInfo, logFilePath, FileMode.Append);
}

    ' Processes the messages that have been buffered.
    ' It is called by the ASP.NET when the flushing of 
    ' the buffer is required according to the parameters 
    ' defined in the <bufferModes> element of the 
    ' <healthMonitoring> configuration section.
    Public Overrides Sub ProcessEventFlush(ByVal flushInfo _
    As WebEventBufferFlushInfo)

        ' Customize event information to be sent to 
        ' the Windows Event Viewer Application Log.
        customInfo.AppendLine( _
        "SampleEventLogWebEventProvider buffer flush.")

        customInfo.AppendLine(String.Format( _
        "NotificationType: {0}", _
        GetNotificationType(flushInfo)))

        customInfo.AppendLine(String.Format( _
        "EventsInBuffer: {0}", _
        GetEventsInBuffer(flushInfo)))

        customInfo.AppendLine(String.Format( _
        "EventsDiscardedSinceLastNotification: {0}", _
GetEventsDiscardedSinceLastNotification( _
flushInfo)))

        ' Read each buffered event and send it to the
        ' Application Log.
        Dim eventRaised As WebBaseEvent
        For Each eventRaised In flushInfo.Events
            customInfo.AppendLine(eventRaised.ToString())
        Next eventRaised
        ' Store the information in the specified file.
        StoreToFile(customInfo, logFilePath, _
        FileMode.Append)
    End Sub

Remarks

The ProcessEventFlush method processes the messages that have been buffered. ASP.NET health monitoring calls the method when the flushing of the buffer is required. The intervals at which flushing is required is determined by the parameter value of the bufferMode attribute in the providers element in the healthMonitoring configuration section.
